Programmable Reference Divider (R-Counter)
If the control bits are “10”, data is transferred from the 20-bit shift register into a latch, which sets the 6-bit R-counter. The serial

Receiver Functional Description
The simplified block diagram below shows the mixer, IF amplifier, limiter, and discriminator. In addition, the DC compensation cir-
cuit, doubler, and voltage regulator for an external LNA stage are shown.
